prude's death a homicide, ruling that he died by complications of asphyxia in the setting of physical restraint, excited delirium and pcp intoxication. >> what i saw in that video was a man who needed help, a man who needed compassion, a man who needed humanity. he lost his life because of the actions of our police officers. >> reporter: prude's daughter tashyra today demanding the officers be held accountable. >> i want justice. i want these officers charged with murder. nobody deserves to die when they are in need. >> reporter: an attorney for the family says they plan to take civil action. >> asking for help in this country has become a death sentence when police become involved. >> reporter: and prude's daughter today has a message about her father. >> i knew him as a caring, energetic and happy go lucky man who enjoyed making everybody smile and who loved his kids. >> all right, adrienne bankert joins us now.

states to be ready by november 1st to distribute a possible vaccine, dr. anthony fauci today saying it's unlikely we will know if we have a safe and effective vaccine before november. >> i think most of the people feel it's going to be november, december. it is conceivable that you could have it by october, though i don't think that that's likely. >> reporter: the race for a vaccine all the more urgent as new outbreaks threaten college campuses and towns. more than 1,000 cases and counting at the university of south carolina. at indiana university, 30 greek houses are quarantined and the school is extremely concerned it is seeing uncontrolled spread. >> i think you just hear around the grapevine people getting it. and then you're like, oh, this person came in contact with this person. >> reporter: after scenes like this outside offcampus bars at west virginia university and the university of oklahoma in norman, some students are worried. >> we have campus corner, which is the block right next to campus, and that's all of our bars and stuff. and there's no masks there. so, if you don't get it here, you're going to get it somewhere in norman and bring it to campus. >> reporter: and just days after

hate only hides. it only hides. and when someone in authority breathes oxygen under that rock, it legitimizes the dark side of human nature. >> reporter: this is biden's second trip to a battleground state this week, after spending most of the past five months at home in delaware. a new poll shows him up eight points in wisconsin. but biden knows what happened to hillary clinton four years ago. she never campaigned in wisconsin and wisconsin went for donald trump. >> all right, mary bruce joins us now from washington. and mary, i want to turn to another headline tonight. president trump sticking with his law and order message, he's now threatening to strip federal funding from cities that have seen an uptick in violence, including new york? >> reporter: tom, this is a political move that is certain to be challenged in court. the president saying, quote, my administration will not allow federal tax dollars to fund cities that allow themselves to deteriorate into lawless zones. leaders of those cities are

outraged, calling this a political stunt to distract from trump's handling of the pandemic. tom? >> mary bruce with news from the campaign trail. mary, thank you. and tonight, president trump is trying to explain after he suggested that voters in north carolina vote by mail, then vote in person. that prompted north carolina's board of elections to issue a reminder that voting twice is illegal and tonight, the new warning from the department of homeland security about russia and the u.s. election. here's abc's chief white house correspondent jonathan karl. >> reporter: tonight, in a new bulletin to law enforcement, the department of homeland security warns that russia is trying to "undermine public trust in the electoral process" by spreading disinformation that mail-in voting creates "vast opportunities for voter fraud." the russian propaganda mirrors what president trump has been saying. he even suggested that people try to vote twice -- by mail and in person. >> send in your ballots, send them in strong, whether it's solicited or unsolicited. the absentees are fine.

we have to work to get them, you know, mean something. you send them in, but you go to vote and if they haven't counted it, you can vote. so, that's the way i view it. >> reporter: on cnn, the attorney general was asked to explain. >> if somebody mailed in a ballot and then actually showed up to vote in person, that would be illegal. >> i don't know what the law on the particular state says. >> you can't vote twice. >> reporter: today, in a series of tweets, the president tried to clarify. "sign and mail in your ballot as early as possible. on election day or early voting, go to your polling place to see whether or not your mail-in vote has been tabulated. if it has not been counted, vote. which is a citizens right to do." twitter slapped a warning on those tweets, saying they violated rules on "civic and election integrity." the head of the north carolina board of elections urged people not to take the president's advice. she said people who vote by mail should not also come to the polls on election day, saying

that would be unnecessary and, quote, would lead to longer lines and the possibility of spreading covid-19. she also, tom, offered a reminder that it is a felony to vote twice in the same election. >> all right, jon, thank you. overseas now, to beirut, lebanon, and the desperate search in the rubble of a building destroyed in that horrific blast, you may remember, a month ago. a sniffer dog alerted search and rescue crews to a possible sign of life. and tonight, crews are hoping they'll find a survivor. here's abc's james longman. >> reporter: one month to the day since this massive explosion rocked beirut, and tonight, they're digging for hope, with reports of survivors in the rubble. a possible heartbeat, somewhere under this mess, is the rescue workers' focus. one volunteer says signs of breathing and a thermal trace have been found. the signal was detected thursday by sniffer dog flash, who helped in the chilean mining rescue. and its caused a flurry of activity in the city's most devastated neighborhood. with some using their hands to help dig.

the august 4th explosion was caused by nearly 3,000 tons of ammonium nitrate, which somehow ignited at the port. it ripped through the lebanese capital, killing at least 200 people and injuring more than 6,000. a supersonic blast wave damaged thousands of homes across the city. and tonight, a chilling discovery. a further 4 tons of the deadly material has been uncovered moments from the original blast site. rescuers are now bringing in a crane to try to lift some of the heavier masonry. beirut is often a divided city, but there's only one prayer being offered up tonight. tom? >> a miracle if it becomes a reality. all right, james, thank you. and back here now, 24 hours after one of the best days on wall street since the covid shutdown, the dow falling more than 807 points, nearly 3%. the nasdaq and s&p both plunging from record highs. investors taking profits on tech stocks that have driven that surge. there's still much more ahead on "world news tonight" this thursday. the tornado watch and warning as we come on.
